Presidential Election Forecast Philosophy
Our US Presidential Election forecast is based on polling in individual states. We run a monte-carlo simulation across the entire country and then calculate the probability of each candidate winning each state or electoral district (in the case of Maine and Nebraska). From this we allocate Electoral College votes State by State giving a final total for each candidate.
Do you allocate whole States / Districts to Candidates?
We run 10,000 simulations of the election. Our seat forecast is based on allocating the total EC votes for each State / District to the candidate who “wins” in each simulation. From this we produce a probability distribution of likely outcomes across all the simulations in aggregate.
Some prediction sites like FiveThirtyEight or Nate Silver have a different probability of Trump winning. What are you doing wrong?
Nothing! We all have slightly different modelling philosophies which produce different outcomes.
Can you tell me what the probability of a certain event happening is?
Sure. We provide the most interesting probabilities above, but leave a comment below if there is a particular probability you want us to share with you.
